What type of animation uses symbols to create movement, size changes, fades, and color effects?

The type of animation that utilizes symbols to create effects such as movement, size changes, fades, and color effects is known as motion tweening. In this technique, a symbol (which can be a graphic, movie clip, or button) is animated over a specified number of frames. By creating keyframes at the starting and ending points of the desired change, the software automatically generates the intermediate frames, producing smooth transitions.

This is particularly effective for creating complex animations with less manual effort compared to frame-by-frame animation, where each frame is drawn or manipulated individually. Furthermore, motion tweening allows for parameters like rotation, scaling, and color effects to be easily adjusted, thereby enhancing the flexibility and dynamism of animations created in Adobe Animate.
